Course abstract
The aim of the course is to create and develop geometrical logic, spatial thinking and imagination, to get acquainted with the terminology of engineering graphics, to obtain extended understanding on the concept of computer aided design and spheres of usage in solving of engineering problems, as well as basic principles of computer aided system selection, to promote the use of standards (LVS, ISO, etc.) in creation of technical documentation. Practically students acquire the possibilities of drawing of different components using AutoCAD software package.
Learning outcomes and their assessment
Knowledge – understands the projection method, view and section view creation principles. Familiar with the drawings related standards (ISO, LVS, etc.). Knows the types of components and the corresponding work documentation and its execution sequence. Able to explain the drawing and to add dimensions and annotations of threads, surface roughness and material. Knowledge on the concept of computer aided design and spheres of different CAD system application, the basic principles of computer aided systems selection. Knowledge is assessed in Test 1, practical works and exam.
Skills – can accomplish part working drawings, axonometric views, perform drawings of dismountable and rigid assemblies and bill of materials for it, as well as read assembly drawings and detailing them according LVS, EN, ISO, etc. standards. Skills to choose an appropriate software application related to the computer aided design sphere basing on the problem nature, to use the software in creating of technical documentation. Able to work with standardized product library elements. Skills are assessed in Homework 1 and 2, Test 2, practical works and exam. Competence, working in group or independently, to use the information technology facilities for the solving of engineering problems and to manage them, as well as to convince others and argue own viewpoint. Competences are assessed in practical works and tests.

Requirements for awarding credit points
Students receive a successful assessment if they have completed the tasks assigned in practical works and homework, have passed 2 tests, and the exam. The tasks performed in the practical works have to be presented. Presentation includes short oral report of each finished task as well as answers to the questions about the theoretical aspects of this topic. Theoretical knowledge is assessed as a test.
Description of the organization and tasks of students’ independent work
Construction of joints. Drawing a detail drawing using complex sections. Construction of surface intersection lines in detail drawing. Drawing of threaded parts.
Criteria for Evaluating Learning Outcomes
A successful assessment can be obtained in tests if there are no significant errors in the drawings of the parts/assembly and at least 50% of the test questions have been answered correctly. All tasks in practical and independent work must be completed, well-formatted, and the student must be familiar with the sequence of work and be able to answer questions. 50% of the total course assessment is made up of points obtained during the semester for practical work, homework and tests, and 50% – points obtained in the exam.
